In the past decade or so, significant advances were made in the field of Future Internet Architecture (FIA) design. Undoubtedly, the size of Future Internet will increase tremendously, and so will the complexity of its users’ behaviors. This advancement means most of future Internet applications and services can only achieve and demonstrate full potential on a large-scale basis. The development of network testbeds that can validate key design decisions and expose operational issues at scale is essential to FIA research. In conjunction with the development and advancement of FIA, cyber-infrastructure testbeds have also achieved remarkable progress. For meaningful network studies, it is indispensable to utilize cyber-infrastructure testbeds appropriately in order to obtain accurate experiment results. That said, existing current network experimentation is intrinsically deficient. The existing testbeds do not offer scalability, flexibility, and realism at the same time. This dissertation aims to construct a hybrid system of conducting at-scale network studies and experiments by exploiting the distributed computing ability of current testbeds. First, this work presents a synchronization of parallel discrete event simulation that offers the simulation with transparent scalability and performance on various high-end computing platforms. The parallel simulator that we implement is configured so that it can self-adapt for the performance while running on supercomputers with disparate architectures. The simulator could be used to handle models of different sizes, varying modeling details, and different complexity levels. Second, this works addresses the issue of researching network design and implementation realistically at scale, through the use of distributed cyber-infrastructure testbeds. An existing symbiotic approach is applied to integrate emulation with simulation so that they can overcome the limitations of physical setup. The symbiotic method is used to improve the capabilities of a specific emulator, Mininet. In this case, Mininet can be used to run applications directly on the virtual machines and software switches, with network connectivity represented by detailed simulation at scale. We also propose a method for using the symbiotic approach to coordinate separate Mininet instances, each representing a different set of the overlapping network flows. This approach provides a significant improvement to the scalability of the network experiments.

The goal of the thesis is to examine and assess actual portfolio of products on the market for server visualization and to compare performance of individual products with performance of the physical machine. The research and the assessment of the actual portfolio will be carried out with the focus on current trends in the area of server virtualization, reasons for realization, and important aspects for their successful implementation. The comparison will be carried out in areas of supported platforms, hardware emulation spectra, hardware limitations, licensing and prices. Further it will be performed comparison in the form of benchmark performance in areas of CPU, RAM, hard-drive throughput, and network throughput of most commonly used products for server virtualization.

The survey deals with still active projects which start at the beginning of last year. These projects show new trends and possibilities in this area. From twelve project were selected four interesting of them (ARCOMEM, ENSURE, TIMBUS, SCAPE) which are subsequently described from different perspectives, compared and evaluated.

Connected systems are becoming more ingrained in our daily lives with the advent of cloud computing, the Internet of Things (IoT), and artificial intelligence. As technology progresses, we expect the number of networked systems to rise along with their complexity. As these systems become abstruse, it becomes paramount to understand their interactions and nuances. In particular, Mobile Ad hoc Networks (MANET) and swarm communication systems exhibit added complexity due to a multitude of environmental and physical conditions. Testing these types of systems is challenging and incurs high engineering and deployment costs. In this work, we propose a scalable MANET emulation framework using virtualized internet infrastructures that generalizes an assortment of application spaces with diverse attributes. We then quantify the architecture using various evaluation techniques to determine both feasibility and scalability. Finally, we developed a hardware offload engine for virtualized network systems that builds upon recent work in the field.

This work takes a look at existing hardware reimplementations of the Amiga 500 home computer and examines the possibility of implementing a similar solution based on the Minerva a and Pipistrello development platforms. The result of this work is an emulator od the Amiga 500 based on a combinator of both platforms.

The goal of this thesis is design of platform capable of sensor output emulation. The platform allows to emulate either digital sensors, communicating over UART, SPI, I2C, CAN and RS-485 buses, or analog sensors and sensors with frequency output.

This licentiate thesis argues that a key to understanding the embodiment of cognition is the “sharing” of neural mechanisms between sensorimotor processes and higher-level cognitive processes as described by simulation theories. Simulation theories explain higher-level cognition as (partial) simulations or emulations of sensorimotor processes through the re-activation of neural circuitry also active in bodily perception, action, and emotion. This thesis develops the notion that simulation mechanisms have a particular representational function, as off-line representations, which contributes to the representation debate in embodied cognitive science. Based on empirical evidence from neuroscience, psychology and other disciplines as well as a review of existing simulation theories, the thesis describes three main mechanisms of simulation theories: re-activation, binding, and prediction. The possibility of using situated and embodied artificial agents to further understand and validate simulation as a mechanism of (higher-level) cognition is addressed through analysis and comparison of existing models. The thesis also presents some directions for further research on modeling simulation as well as the notion of embodied simulation as off-line representation. / <p>Report code: LiU-Tek-Lic-2007:21.</p>

Historically, compression was primarily used as a preventative measure to reduce the risk of clipping or overloading equipment in the recording signal chain. Research on the topic has revealed that modern production applications more commonly include utilizing compression as a creative effect, to impart distortion, manipulate timbre, and modify transients, rather than to control the dynamic range of audio signals. It has also been found that specific compressors are regularly chosen for the sonic signatures that they impart onto audio material. To evaluate the quality of a digitally modeled emulation plugin of a classic compressor, an analog and digital version of the Universal Audio 1176 FET compressor was tested in this study. 20 experienced listeners participated in a MUSHRA-style listening test during which processed sounds were rated based on four attributes. The result of the listening test verifies previous findings on the sonic signature of the 1176, and evidence presented suggests that the plugin can be used for the same creative purposes as the analog device. However, it was also found that intuitive methods could not be used when trying to match the processing of the hardware. Instead, critical listening and user experience seem to be important factors when trying to achieve the same creative effects when using the software plugin.
